Anticoagulant rodenticides had an antidote in case of accidental poisoning while bromethalin has none and bromethalin products are readily palatable to dogs and cats. For dogs and cats, however, this is only a small advantage as pets commonly consume the insecticide directly. This is good news for owls, hawks, and other rat-consuming wildlife. Because only small amounts are needed to kill a rodent, a predator is unlikely to be harmed by consuming a bromethalin-poisoned rodent. Demand for safer products rose.īromethalin was supposed to represent a better choice. The EPA demanded that these types of poisons be phased out and presently they are only available to commercial exterminators. Either group of animals might consume the poisons outright or might become poisoned by eating an already intoxicated rodent. Problems with them included toxicity when they were consumed by pets or by predatory wildlife accidentally. These products were readily consumed by rodents and after 5 days or so, they induced internal bleeding and death. In the past, anticoagulant rodenticides, which were effective and available in virtually every hardware and garden store, were the most common rat poisons in the U.S. Rat poisons as well as traps are widely used to control rodent populations in human communities all over the world. Wild rodents consume our crops, destroy our fabric and paper products, bring disease and are generally unsanitary in our homes.
Rodent control has been paramount in human civilization for centuries if not millennia.
